Add the path to the Django project to the Tornado application's PYTHONPATH env-var and set DJANGO_SETTINGS_MODULE appropriately. You should then be able to import your models and use then as normal with Django taking care of initial setup on the first import.

You shouldn't require any symlinks.

and you can read <a href="http://lincolnloop.com/blog/2009/sep/15/using-django-inside-tornado-web-server/">Using Django Inside the Tornado Web Server</a> for some information. the following code has taken from there:

I could not get it to work with the information provided by @aragon in Django 1.8. Since this question is one of the top results in Google when searching for Django + Tornado integration, here is how I got it to work in Django 1.8:

<pre><code>from django import forms
from django.db import models

from models import Operation #Own model
import django

DATABASES = {
'default': {
 'ENGINE': 'django.db.backends.sqlite3',
 'NAME': 'database.db',
 }
}
settings.configure(DATABASES=DATABASES)

if django.VERSION[:2] &gt; (1,5):
 django.setup()
</code></pre>

I have an existing Django application with a database and corresponding models.py file.

I have a new Tornado application that provides a web service to other applications. It needs to read/write from that same database, and there is code in the models file I'd like to use.

How can I best use the Django database and models in my Tornado request handlers? Is it as simple as making a symbolic link to the models.py Django project folder, importing Django modules, and using it? I guess I'd have to do settings.configure(), right?

Thanks!
